The length of time you may remain in the United States on exchange visitor status is determined by the general limitations for the category and the length of time needed to complete the exchange objectives. These limitations apply to the total length of stay as an exchange visitor. USCIS allows exchange visitors an additional grace period of 30 days to prepare for departure from the United States. It is important to be aware that the exchange activity and any related employment are permitted only until the ending date on the Form DS-2019. During the additional 30 days your status will be much like that of a tourist in that you may remain and travel in the U.S. If you transfer from one program sponsor to another, you cannot use that transfer to prolong your stay in the United States beyond the limitations of the pertinent category.
